Maybe my brain is out to lunch, but I think the only thing you will get from projecting points and curves onto a curve will be points - except for the unique case where you have a curve that is at least a piece of an identical curve in the exact relationship and projection direction to the first curve that the projection would lie on top of the first curve. And that case seems fairly trivial to me.

Correct. The points are what I’m looking for. Or when part or all of the curve to be projected is aligned in the projection direction with the target curve in which case a curve results

Sorry I missed your detail … but there are lots of processes where I have to make an extra piece of construction geometry. Its nice to save some time, but we are just talking about two steps vs. one step.
